在ASP.net里添加 javascript

来源：互联网发布：mysql怎么删除表字段编辑：程序博客网时间：2024/04/29 01:27

Page.RegisterStartupScript("sf", "<script language='javascript'>location.replace('#');</" & "script>")

</script>必须分开，否则会和ASP.net 的结束符冲突(ASP.Net 1.0)

还有一个是 RegisterClientScriptBlock
RegisterClientScriptBlock一般返回的是客户端函数的包装，而RegisterStartupScript返回得函数在document装载完成后会执行，类似于我们平时所说的body onload="f()"里面的函数；这两个方法在客户端呈现的代码位置不同，RegisterClientScriptBlock在<form runat=server>之后，而RegisterStartupScript在</form>之前。

给控件添加 javascript 事件

btnSave.Attributes.Add(“onclick”,”Javascript:return confirm(‘Are you sure to save?’);”)

给DataGrid添加javascript

Sub ItemDataBound(ByVal sender As Object, ByVal e As DataGridItemEventArgs)

If e.Item.ItemType <> ListItemType.Header And e.Item.ItemType <> ListItemType.Footer Then

Dim oDeleteButton As LinkButton = e.Item.Cells(5).Controls(0)

oDeleteButton.Attributes("onclick") = "javascript:return Confirm ('Are you sure you want to delete" & DataBinder.Eval(e.Item.DataItem, "m_sName") & "?')"

End If

End Sub

按Button后，弹出alert框 (ASP.Net 2.0)

在成功后加：

ClientScript.RegisterStartupScript(Me.GetType(), "MyScript", "<script language='javascript'>alert('Send successfully.');</script>")
